Question

PLEASE HELP ME ANSWER

Answer 1

x = -1.47, 6.47

Explanation:

x = 5 + i√63 / 2, x = 5 - i√63 / 2

√63 = 7.94

x = 5 + i(7.94) / 2, x = 5 - i(7.94) / 2

as i = -1

x = (5 - 7.94) / 2, x = (5 + 7.94) / 2

thus, x = -1.47, x = 6.47

Answer 2

The answer is down below

Explanation:

`x = (5 + i √(63) )/(2) \: or \: \: (5 - i √(63) )/(2)`

`x = (5 + 3i √(7) )/(2) \: or \: (5 - 3i √(7) )/(2 )`
